excellent article sir! i have been chastised for suggesting that the world no longer needs tribalism.
i think you carried forth the argument more clearly and thoroughly. humans are social animals, but any situation can become healthy and dynamic or unhealthy and destructive.

to answer the post above - some native american tribes had a member who was a 'contrary'. it was believed (i'll do my best here) that the tribe's overall health and balance was maintained by having someone in a mirroring role. i refer you to the asian practice of turning one column upside down when constructing a temple to make sure it has no weakness. i'll leave it there - if i try to explain i'll sound stupid to at least half of you!
